An improved crutch includes an improved shock absorbing mechanism, lighting components, and an improved tip component. The improved shock absorber mechanism utilizes compressible spheres that are compressed when a person supports all or partial of their body weight onto the crutch and are uncompressed when the weigh is removed. This compression of the spheres absorbs any impact from the walking surface to the person's body. The elasticity of the compressible spheres is adjusted by forming a central through-opening through the sphere, varying the number of the sphere, their diameter and material.
